Previously, when this sample is added, commit1c47910ef8("samples/bpf: add perf_event+bpf example"), a symbol 'sys_read' and 'sys_write' has been used without no prefixes. But currently there are no exact symbols with these under kallsyms and this leads to failure. This commit changes exact compare to substring compare to keep compatible with exact symbol or prefixed symbol. Fixes:1c47910ef8("samples/bpf: add perf_event+bpf example") Signed-off-by: Daniel T.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
